Time / Date problem

[tsecher]

$born = '2006-01-17';

$kill = date('Y-m-d',mktime(0, 0, 0, date("m",$born), date("d",$born)+180, date("Y",$born)));

echo $kill;

Why doen't this work? I want the code to calculate a given date ($born) + 180 days.

date() [php.net] expects a timestamp, not a string. Check out strtotime() [php.net] as one way to convert your string date into a timestamp.

Use strtotime:

Get the unixtime for born and add 180 times # seconds in a day:

$born = '2006-01-17';
$kill = date('Y-m-d',strtotime($born) + (180 * 86400));
echo $kill;

Check strtotime function what the exact string format should look like.

Welcome to WebmasterWorld, tsecher.

I see that you figured out that it is possible to use date() and mktime() together to find dates in the future. As the others have noted, you need to pass this function a timestamp and there are a number of ways to accomplish the task at hand. Another common method is to extract the pieces you need:

$born = '2006-01-17'; 
list($year, $month, $day) = explode [php.net]('-', $born); 
$kill = date('Y-m-d', mktime(0, 0, 0, $month, $day + 180, $year)); 
echo $kill;

Another member recently asked a similar question -- this thread may interest you, especially if that $born variable value is coming from a database:
